Brass Fittings

<h3>About Brass Fittings by Midland Industries</h3><p>When it comes to reliable fluid and gas transfer, the quality of your fittings matters as much as the quality of your pipe or hose. <strong>Brass Fittings</strong> — rooted in the Jamnagar manufacturing tradition and distributed through Midland Industries — represents a benchmark in precision-engineered connection hardware for industrial, automotive, plumbing, and outdoor equipment applications.</p><p>Jamnagar, India, has long been recognized as one of the world's premier centers for brass component manufacturing, and this brand draws on that deep metallurgical expertise. Using state-of-the-art CNC machinery and rigorous quality control practices, Brass Fittings produces components that meet demanding dimensional tolerances and pressure ratings across a wide range of thread standards — including NPT, NPTF, BSP, and metric — making them compatible with both domestic and international systems.</p><h3>A Comprehensive Fittings Lineup</h3><p>The core of the catalog is an extensive range of <a href="/7273-brass-fittings-pipe-fitting-17358">pipe fittings</a>, encompassing elbows, tees, unions, couplings, bushings, nipples, caps, and crosses in a variety of sizes and configurations. These are the workhorses of any plumbing, pneumatic, or hydraulic system — connecting runs of pipe securely while maintaining leak-free performance under pressure.</p><p>For applications where both pipe and hose connections are needed in the same system, the brand&apos;s <a href="/7273-brass-fittings-brass-bronze-pipe-hose-fittings-201742">brass and bronze pipe &amp; hose fittings</a> offer versatility and corrosion resistance in a single product family. Bronze alloys are particularly valued in marine, chemical, and high-humidity environments where dezincification resistance is critical. Whether you need hose barbs, flare fittings, compression fittings, or forged adapters, this lineup covers the full spectrum of connection styles.</p><p>Recognizing that not every application calls for metal, Brass Fittings also offers a selection of <a href="/7273-brass-fittings-nylon-pipe-hose-fittings-200724">nylon pipe &amp; hose fittings</a> designed for lighter-duty fluid transfer needs. Nylon fittings are a smart choice where chemical compatibility, weight savings, or electrical non-conductivity are priorities — common requirements in automotive fuel systems, agricultural equipment, and marine auxiliary systems.</p><h3>Why Choose Brass Fittings?</h3><ul><li><strong>Material quality:</strong> Free-cutting brass alloys (such as IS 319 / C36000) are used throughout, delivering excellent machinability and long service life.</li><li><strong>Wide thread compatibility:</strong> NPT, NPTF, BSP, metric, and other thread forms are available to suit virtually any system.</li><li><strong>Broad application range:</strong> Suitable for water, gas, oil, pneumatic, and hydraulic service across automotive, industrial, and residential settings.</li><li><strong>Finish options:</strong> Natural brass, nickel-plated, and tin-plated finishes are available depending on the environmental demands of the application.</li><li><strong>Extensive SKU depth:</strong> With hundreds of parts across multiple fitting types and sizes, it&apos;s easy to source everything needed for a single project from one brand.</li></ul><p>Whether you are maintaining a vehicle&apos;s fuel or coolant lines, plumbing a workshop compressor, or outfitting marine equipment, Brass Fittings delivers the precision and durability that professionals and serious DIYers depend on.</p>

Product Details

The Brass Fittings RB3412 is a hex bushing designed to connect two threaded pipe components with different diameters. This reducer bushing features 3/4" male NPT (National Pipe Thread) on one end and 1/2" female NPT on the other, allowing you to step down from a larger to smaller pipe size in plumbing and fluid transfer applications.

Key Features:

  • Constructed from durable white nylon material for chemical resistance
  • Hexagonal design provides increased grip surface for easy installation with a wrench
  • 3/4" MPT x 1/2" FPT thread configuration
  • Suitable for use with water, agricultural chemicals, non-acid fertilizers, petroleum fuels, and ethanol
  • Temperature rating up to 175°F (79°C)
  • Pressure rating up to 150 PSI

This nylon hex bushing is ideal for agricultural spraying systems, marine applications, RV plumbing, and general fluid handling where corrosion resistance and chemical compatibility are important. The white nylon construction offers excellent resistance to most agricultural chemicals and petroleum-based products while remaining lightweight and cost-effective.
